 We've test Magnetic Fields Sensor for Android Mobile phone.( LG Optimus One P500 )

public class

GeomagneticField

extends Object

java.lang.Object
↳	android.hardware.GeomagneticField

Class Overview

This class is used to estimated estimate magnetic field at a given point on Earth, and in particular, to compute the magnetic declination from true north.
This uses the World Magnetic Model produced by the United States National Geospatial-Intelligence Agency. More details about the model can be found at http://www.ngdc.noaa.gov/geomag/WMM/DoDWMM.shtml. This class currently uses WMM-2010 which is valid until 2015, but should produce acceptable results for several years after that. Future versions of Android may use a newer version of the model.
